Effective Peripheral Treatments: What Really Works?

Do you often feel anxious? Struggling to concentrate at work? Do you wake up drenched in sweat? Welcome to a phase that is frequently overlooked and often chaotic.

This transitional stage, marked by menopause symptoms but not yet completed, was once brushed off as a fleeting hormonal shift. Today, it’s increasingly acknowledged as a challenging and disruptive decade during which significant changes occur within the body and mind.

Emotional ups and downs, migraines, fluctuations in heart rhythms, urinary tract infections—an array of symptoms can leave many feeling unacknowledged. Fortunately, as our grasp of hormonal health evolves, emerging treatments are providing essential relief.

Nonetheless, there’s no shortage of noise. Social media is awash with advice on remedies, ranging from dietary supplements to intricate exercise routines. What genuinely benefits you, and what is merely a waste of time and money?

The answer depends on your personal experience of the perimenopause phase. During this time, estrogen levels fluctuate unpredictably, accompanied by declines in progesterone and testosterone, impacting everything from bone density and muscle strength to cognitive function and cardiovascular health.

Despite the fact that half the population goes through this transition, its significance is often underestimated. “Menopause marks a pivotal moment in a woman’s life—physically, emotionally, and socially,” states Christina del Toro Badsa, a physician and expert in hormonal health based in Atlanta, Georgia. “However, many women belong to the ‘sandwich generation,’ caring for both children and aging parents while their own well-being is often neglected.”

These symptoms go beyond personal struggles; they can have far-reaching social implications. According to a survey by British charities regarding welfare, one in four women considers leaving their job due to menopausal symptoms. In the U.S., a 2025 study estimates that the costs associated with reduced working hours or premature retirement due to menopause amount to $1.8 billion annually.

Many individuals experiencing perimenopausal symptoms opt for HRT

In terms of solutions, the UK’s National Institutes of Health (Nice) identifies hormone replacement therapy (HRT) as the first-line treatment for those over the age of 40. However, despite its efficacy, the adoption remains inconsistent, and its use in the U.S. has dramatically fallen over the last quarter-century. This decline is partly due to long-standing fears surrounding side effects revealed in two studies. A significant HRT trial in 2002 was halted after early results suggested an increased risk of breast cancer, heart attacks, and strokes. A follow-up in 2003 estimated that HRT was linked to 20,000 breast cancer cases in the following decade.

While these trial findings were not incorrect, they had limitations and were misunderstood. Media reports, for instance, focused on women over 60. Later trials indicate that the age at which women start HRT significantly influences their breast cancer risk. For example, five years after stopping HRT, women who have taken HRT for less than 5 years show no increased risk of breast cancer.

Context is key. According to the British Menopause Society, women aged 50-59 using HRT (both estrogen and progestogen) for up to 14 years may see an additional 10 breast cancer diagnoses per 1,000. However, this “minor risk” must be evaluated against the substantial reduction in endometrial cancer risk provided by HRT. This risk is comparable to several lifestyle factors, such as obesity, which adds 10 additional breast cancer diagnoses per 1,000 women in the same age group, while consuming 4-6 units of alcohol daily increases cases by eight. In short, while HRT slightly raises the likelihood of breast cancer diagnosis, it is not substantial compared to various other lifestyle choices.

Advantages of HRT

Furthermore, HRT offers several benefits, including lowering the risk of cardiovascular diseases and reducing fracture rates. Initial research suggests that estrogens may be crucial in assisting the brain with glucose metabolism regulation, potentially explaining fatigue and memory lapses during perimenopause due to estrogen depletion affecting glucose processing. Additionally, studies by Roberta Brinton from the University of Arizona indicate that HRT may provide some protection against Alzheimer’s disease—a notion that remains controversial.

“All menopause guidelines indicate that hormone replacement therapy is the most evidence-based treatment for perimenopausal symptoms,” asserts Louise Newson, a physician and member of the UK government’s menopause task force.

Still, HRT isn’t suitable for everyone. Some women may have additional risk factors that prevent their use of HRT, such as prior history of lupus or blood clots, while others may hesitate due to perceived associated risks. For instance, researchers like Karyn Flick from the University of Wisconsin-Milwaukee are studying highly selective estrogen receptor drugs. Unlike current HRTs, which activate a broad range of estrogen receptors, these drugs target only those linked to protective effects, such as inhibiting the growth of breast and ovarian cancer. Initial studies suggest this method could be more effective than existing treatments.

Nice also recommends cognitive-behavioral therapy (CBT) as a frontline strategy during the perimenopausal phase. Clinical trials indicate that CBT can effectively diminish hot flashes and night sweats.

On the topic of hot flashes, drug developers are making strides. In 2023, the FDA approved Fezolinetant, the first non-hormonal medication designed for this issue. It operates by blocking NK3 receptors in the brain that control the body’s internal thermostat in low estrogen conditions. “This medication works quickly and effectively,” explains Alyssa Dweck, a consultant gynecologist and chief medical officer at Bonafide Health, a US-based company specializing in menopause products. The downside is the high cost, unsure insurance coverage in the U.S., and the necessity for regular liver monitoring due to potential side effects.

A more promising alternative may be Elinzanetant, a similar drug that received approval in July from the UK’s regulatory agency. It targets both NK1 and NK3 receptors, and early trials suggest it not only reduces moderate to severe hot flashes, but also alleviates sleep disorders without inducing liver toxicity.

Is Increasing Protein Intake Necessary During Menopausal Transition?

Medical intervention is just one component of the solution. Dietary changes can also be beneficial. Many influencers advocate for “increased protein intake,” which may hold some truth during the perimenopause. Although most individuals meet their protein requirements with a balanced diet, hormonal shifts during perimenopause can lead to bone and muscle loss, causing some women to gain weight for unclear reasons.

Arthur Conigrave from the University of Sydney suggests that the disparity between the body’s protein needs and actual intake could be a contributing factor. In a 2022 study, he and his colleagues found that as muscle protein breaks down, the brain compels a person to eat more to restore protein levels. However, without dietary adjustments to boost protein percentage, many end up eating more carbs and gaining weight.

The Conigrave research team posits that during the perimenopausal phase, women might need to boost their daily protein intake by approximately 0.1 to 0.2 grams per kilogram of body weight. For a person weighing 70 kg (about 155 lbs), that’s an extra 7g to 14g of protein each day—equivalent to a large egg or a cup of edamame.

Do Supplements for Perimenopause Actually Deliver Results?

Despite the hype, scientific evidence supporting supplements for perimenopausal symptom relief is sparse. A 2021 review identified only one extract, Cimicifuga racemosa, or Black Cohosh, as having considerable evidence for effectiveness; research suggests it may alleviate anxiety, irritability, and hot flashes. This might be due to increased serotonin levels, but results vary widely. Safety remains uncertain. Vitamin B6 may lessen hot flashes and protect against cognitive decline, while maintaining optimal vitamin D levels can bolster mood and immune function. Nevertheless, these supplements may not yield transformative effects.

Weightlifting during perimenopause can positively influence bone density.

“Certain vitamins and supplements can alleviate some symptoms, but they cannot replace missing hormones or provide the long-term health benefits that HRT offers,” notes Newson. Multiple studies have indicated that HRT reduces the long-term risk of heart disease and diabetes.

Moreover, there’s an increasing interest in the microbiome and its alterations during menopause. A recent review of current research demonstrated that while probiotics show beneficial effects on perimenopause-related bone health, hot flashes, psychological symptoms, and vaginal dryness, many studies still require more robust design to minimize bias.

Should I Focus on Weights or Cardio?

Finally, there’s the question of the most effective exercise regimen to combat the effects of perimenopause. Is it necessary to hit the pavement, or is strength training the better approach? A review of studies from 2015 to 2022 confirmed that weight training during perimenopause enhances strength, bone density, and metabolic health, but it’s still uncertain if this method outperforms other forms of exercise.

In terms of social media “advice,” proceed with caution. Regulators are tightening restrictions on misleading claims, but this area still possesses a Wild West atmosphere. Significant attention and funding are necessary to further understand the conditions affecting women.

How the World Works: A Compelling Case for Becoming an Engineer

Microfluids enable chips such as this to simulate biological organs

How the World Flows

(Oxford University Press, by Albert Folch, now available)

What do rainbows, inkjet printers, human skin, pregnancy tests, and fish gills have in common?

To explore this, you must delve into what Albert Folch, a bioengineering professor at the University of Washington, terms the “liliptian fluid world.” Here, we encounter the fascinating realm of microfluidics, which manages liquids at a miniature scale—from tiny veins in the human body to microchannels etched into lab chips.

Folch’s new book, How the World Flows: Microfluids from Raindrops to COVID Tests, is an astonishing journey through the numerous ways microfluidics influence our world. He credits his neurobiologist wife in the acknowledgments for encouraging him to write about not just microfluidic chips, which have become crucial in chemistry, biology, and medical research, but also about the “device” of microfluidics found in nature.

This allows the book to paint broader pictures, examining both current technologies and historical examples, from handheld DNA sequencing devices to how the tallest trees draw nutrients from the soil. Folch also explains phenomena like capillarity in paper—enabling writing—and discusses the fundamental mechanics of a candle and the workings of an automobile engine.

Each of the 18 chapters is brief and introductory, starting with a personal story about a historical figure, such as inventors, athletes, and chefs, making the material more relatable.

Physics concepts in How the World Flows, like viscosity, surface tension, and gravity, are presented without complex equations but instead through straightforward explanations rooted in real-world contexts.

At times, I’ve yearned for deeper detail regarding the devices and processes Folch discusses. Additionally, the coverage of recent innovations, including chip-sized devices that replicate entire organs, feels somewhat limited compared to the wealth of historical context.

Nevertheless, as I read, I felt I was absorbing a wealth of knowledge about everyday phenomena. Microfluids have become essential in understanding our bipedalism due to sweat, why lakes don’t drain into the Earth, and how all vertebrates can perceive each other’s calls. There’s even a section on the complex engineering found in a mosquito’s proboscis!

Folch’s writing exudes enthusiasm and warmth, though he occasionally slips into the realm of popular science writing that can obscure the overall tone of the book. For instance, many scientific contributions are intertwined with childhood anecdotes, which can shift from relatable to hagiography.

I also found it remarkable that a book could make microfluidics accessible to those without rigorous educational backgrounds.

Despite this, the strength of How the World Flows lies in its diverse cast of characters and its emphasis on the significance of microfluidics in shaping our world.

Above all, this book has the potential to inspire young readers to consider a future in engineering. It also serves as a reminder of the intricate complexity and wonder of any object under a microscope, fueling our curiosity.

Exploring the Works of Science Fiction Master Larry Niven, Author of Ringworld

Ring World Throughout the Times

Ring World
Larry Niven (Golanz)

Ringworld by Larry Niven won both Hugo and Nebula awards in 1970, and received massive acclaim. It has been printed ever since.

It came out when humans had just landed on the moon and we seemed to be heading towards the stars. The title alone evokes a particular golden age of science fiction when (most male) writers wrestled with big physics and big ideas, imagining a distant future in which humans took on galaxy adventures.

Authors like Niven were pride in trying to get science right because they wanted to imagine what was in the universe. and Ring World Features New Scientist This month seemed like a good time to revisit Book Club and novels, and finally read it as a teenager.

How did this 55 year old work stand the test of time? After all, many books from this era are grossly dating. Because science has now made their plotline stupid. Sometimes, because sexual politics (or other cultural aspects) have begun to stink for decades.

First of all, this book is packed with ideas! You can see why it was a smash hit and eventually became part of a vast network of follow-up stories, prequels and spinoffs.

Considering how much internal lore is thrown at us, I found the novel surprisingly zippy and exposition light. Our 200-year-old hero, Louis Gridley Wu, was approached by alien Ness, known as a human-seasoned adventurer and puppeteer, and asked to come to a mysterious mission in exchange for access to new technology.

Ring World Evokes the golden age of science fiction when writers (mainly men) wrestled with big physics and big ideas

Woo and Nessus are to join their adventures with a belligerent “Kuchinti” alien like cats called Speakers and Animals (the animal in question is the other species) and a young human woman named Tierra Brown, who became apparent only later in the story. The gang travels to Ringworld of the same name and crashes after being fired by an ancient security system.

Ringworld is the star of this show. This is an ancient craft on an unthinkable scale. A world of ribbons looped around the stars, 1.6 million kilometers wide and an internal surface area of 3 million Earths. It has a diameter of 305 million kilometers and is made from a material with incredible tensile strength. In the Terra-formed innermost part of Ringworld, civilization has fallen, but life continues.

Woo and the gang have to find a way to move a vast distance across the inside of the ring and leave it. Along the way, as you can imagine, they have a lot of adventures.

There is something modern editors would probably want to cut about this 1970 novel convention, and they may want to give female characters more depth.

Meanwhile, science was thoroughly separated by readers at the time, so Niven’s follow-up, Ring World EngineerThe S, published 10 years later, was a counterargument for all people who understood the fundamental mechanism. Ring World.

This isn’t my favorite Niven. In other words An outdated world. However, revisit Ring World I starved him to return to his universe. I’m going to reaffirm some of his other classics The Mot of God’s Eyesimilarly Ring WorldThere are many interesting questions that you won’t be able to answer in the first book, so there’s a follow-up.

I would recommend Emily too…

Draco Izakaya
Larry Niven (TOR Publishing)

Strictly speaking, this section should be entitled “Larry Niven also recommended.” I recently exchanged emails with him to plan an interview and I asked him which of his books he would specifically recommend to me. He answered immediately Draco Izakaya. I didn’t have time to read it yet, but I’m very happy to be able to share this recommendation with the man himself..

Humanoid mosquitoes, fatal lunar aliens contact, implants that tell you all about your partner … I feel that the science fiction novel provided in February is particularly interesting. Other worlds This year's cold, dark season. You will find it, regardless of whether you are following the classic science fiction such as Gareth L. Powell, Adrian Tchaikovsky, high concept thriller, or future global flooding. enjoy!

After reading Tchaikovsky's excellent science fiction novel Alien clay In the case of a new Scientist Book Club -we are in the middle now, so sign up and participate in us. It's free, I'll talk to Adrian next month! -I'm definitely getting better from this wonderful writer. This latest one is a story of a deadly black moon survival and the first contact, and is crowded with radio activities. When two people have to land in a hostile month, they begin to learn more about the strange species they live there. Our science fiction columnist Emily H Wilson really enjoyed this. Please be careful about next week's review.

Eliya persuades Anna to go to EminMind to celebrate the 10th anniversary. This high -tech company provides implants so that you can hear each other's thoughts. But Anna may have something hidden from her partner … I love the good concept thriller, which is a fun (and terrible) idea.

Powell is the author who won the British Science Fiction Award. Stars and bones and Remaining of warAnd his latest novel sounds like another great slice in hard science fiction. It follows the story of archaeologist Ursula Morrow, who will be infected with alien parasites. Her worries about the danger of her career, do nothing because the Earth is later destroyed and no one really needs an archaeologist. Two years later, she is in a refugee camp in the backwater world when she is in charge of finding an infected alien crafts, hoping that humanity may help survive. 。

I love how wonderful and strange this novel sounds. In 2272, New York and Buenos Aires have been underwater for years, and the Patagonia Islands are the only lands that can live on Earth. Our protagonist is a humanoid mosquito where everyone has a terrible appearance. When the world collapses around him, Dengue's boy looks for the truth about his origin and the meaning of his life. This is translated from Spanish by Rahle Berry, and I think it's surprising!

Many of the earth are underwater for the boy with dengue fever …

I like the sound of this blend of archeology and science fiction. There, you will reach the unexpectedly arriving at the Malboro downs, which is approaching the city of Swindon. Claire Holworth is part of the archeological survey on its origin to manage sites before public pressure to reach the summit.

The blend of this science fiction and thriller will continue to return to the summer cabin of Oregon's family and start again to start again. In the cabin, he discovers Alex, a 10 -year -old girl, Artemis Darth Vader.

I haven't read it yet, so I can't promise that this is a science fiction, but it's compared to the works of speculative fiction writers such as Margaret Atwood, David Mitchell, and Karian Bloodle (Time in time The author), and it sounds very interesting. It is mainly for women who are older or died, but the people around her are scary and the same way through the continent for centuries for centuries. Can she stop? This can be more fearful than science fiction. We will report in both methods.

This time, compared to the Jordan Peal movie, more speculative fear here Stranger Singus -I're very here here. Kara is a 25 -year -old and a passive guardian of 16 -year -old brother Jamie. Meanwhile, she has been suffering from the “nightmare” of Jamie and her siblings, Dre, who continues to die. When Jamie's actions become unable to control, the brothers continue to run and realize that their lives and reality are facing the balance.

Review of Wilmot Works It Out: A Relaxing Puzzle Game Transforming Jigsaw Puzzles into Artistic Masterpieces

WAnthropomorphic squares have a strange but not undesirable presence. He lives in a spacious empty house, where Sam, the friendly local postman, regularly delivers tiled puzzles. A subscription that never expires. Wilmot unpacks each new shipment and scatters the pieces on the bare floor. Then shunt, grab, and rotate each piece to form a coherent picture. Each picture is drawn by British illustrator Richard Hogg. Once the matching pieces snap together and your artwork is complete, you can hang it on Wilmot’s big empty wall. As soon as one puzzle is completed, Sam arrives with another, and soon Wilmot’s walls are as cluttered and colorful as a search gallery.

Usually, when you finish a painting, some debris will remain, so identify these rogue debris, put them aside (you are free to organize the floor space according to your organization’s requirements) and move them back to their original location. Part of the challenge will be to bring it back to . Once you have all the necessary components. Eventually, you’ll be able to do several puzzles at once, each with varying degrees of completion. It’s this arrhythmia that gives the game its unique feel and makes it more than just a digital jigsaw simulator.

Postwoman Sam’s breezy dialogue tells a tender story through lively exchanges, adding a touch of human warmth to the relentless inscrutability. But as well as Witch Beam’s zen 2021 Bafta winner Unpacking, Willmott works fine. It’s almost a therapeutic approach. The puzzles are not difficult or complicated. Rather, it’s a slow, satisfying game that feels like untangling a complicated knot. This effect is calming, like a jigsaw, but there is a little more room for creative flair when it comes to placing artwork.

New Mario Movie in the Works: And I Have the Ultimate Idea to Make it Even Better! | Games

WIn a surprising move, Nintendo made an announcement at the Oscars ceremony revealing its collaboration with Illumination Studios to create another Mario movie on March 10th. The decision was unexpected considering the lack of attention at the event that day. The previous Mario movie was a massive success, grossing $1 billion and marking the end of a cursed era for video game adaptations. The new movie is scheduled for April 2026, with co-directors Aaron Horvath and Michael Jelenic and screenwriter Matthew Fogel returning for the project. Despite this, the film may not necessarily be a direct sequel as both companies have not confirmed its title as a sequel. Nintendo’s Shigeru Miyamoto expressed excitement for “a new animated film based on the world of Super Mario Bros.” promising a bright and fun narrative.

The previous Mario movies faced criticism from movie critics, with mixed reviews on performances such as Jack Black’s Bowser and Seth Rogen’s Donkey Kong. Regardless, the upcoming sequel presents an opportunity to enhance the storytelling and expand the world of Mario beyond nostalgic references.

While the first movie focused primarily on Mario, there are hopes for the sequel to explore other characters and locations within the Mario universe. The lack of a complex storyline in the games provides a blank canvas for the filmmakers to develop a compelling narrative that goes beyond just fan service.

The next Mario movie could potentially expand beyond the Mushroom Kingdom, drawing inspiration from games like Mario Galaxy to create a visually spectacular experience. However, there is still room to explore within Mario’s familiar world, offering an opportunity to push creative boundaries and deliver a more ambitious sequel.
